Iyo dizeli mafuta jekiseni system atomize mafuta uye anoaparadzira pakati pezvikamu zvinosanganiswa nemhepo mukamuri yekupisa.
Inonyanya kuumbwa nejekiseni remafuta uye injector body.Majekiseni emafuta akaiswa pamusoro wecylinder akakamurwa kuva mhando mbiri: yakavhurika mhando uye yakavharwa mhando.Injector yakavhurika ine chimiro chakareruka asi yakashata atomization uye haiwanzo shandiswa.Majekiseni emafuta akavharwa anoshandiswa zvakanyanya mumajini akasiyana siyana edhiziri.Injini yedhiziri inofema mweya wakachena panguva yekutora sitiroko.Kana iyo yekumanikidza sitiroko yava kusvika kumagumo, mafuta edhiziri anowedzerwa kusvika kupfuura 100MPa nepombi yejekiseni yemafuta, inobayiwa muhumburumbira kuburikidza nejekiseni remafuta, uye yakasanganiswa nemhepo yakadzvanywa yekupisa kwepamusoro munguva pfupi kwazvo kuti iite musanganiswa unobvira.Nekuda kwehupamhi hwekutsikirira reshiyo yeinjini dzedhiziri (kazhinji 16-22), mhepo yemhepo mucylinder inogona kusvika 3.5-4.5MPa pakupera kwekutsikirirwa, uye tembiricha yakakwira kusvika 750-1000K (ukuwo gasi musanganiswa wekumanikidza. peturu peturu panguva ino ichava 0.6-1.2MPa, tembiricha inosvika 600-700K), iyo inodarika zvakanyanya kudziya kwekudzima kwedhiziri.Nokudaro, mushure mokunge mafuta edhiziri akaiswa muhumburumbira, anobva atungidza uye anopisa ari oga mushure mekusanganiswa nemhepo munguva pfupi.Mhepo yemhepo mucylinder inokwira nekukurumidza kusvika 6-9MPa, uye tembiricha inokwirawo kusvika 2000-2500K.Inotyairwa nemhepo ine simba guru, piston inofamba ichidzika uye inotyaira crankshaft kuti itenderere kuita basa, uye gasi rekubuditsa rinoburitswawo mumhepo kuburikidza nepombi yekuburitsa.
Iyo yakajairika injini yedhiziri inotyairwa neinjini camshaft, uye mafuta edhiziri anounzwa kukamuri yemafuta yecylinder yega yega kuburikidza nepombi yemafuta inodzvanywa.Iyi nzira yekugovera mafuta inofanirwa kushanduka nekuchinja kweinjini yekumhanyisa, uye huwandu hwakakwana hwekupa mafuta pakumhanya kwakasiyana haugone kuwanikwa.Iyo yakajairwa njanji jekiseni mafuta ekupa system ine yakakwira yekumanikidza mafuta pombi, yakajairika pombi yekupa mafuta, jekiseni remafuta, yemagetsi control unit (ECU) uye mamwe mapaipi ekumanikidza sensors.Imwe neimwe jekiseni yemafuta muhurongwa yakabatana kune yakajairwa mafuta ekufambisa kuburikidza neyayo yakanyanya kudzvanywa pombi yemafuta.Mapombi akabatana, uye pombi yakajairika yekugovera mafuta inoita se hydraulic pressure accumulator yeinjector.Paunenge uchishanda, iyo yakakwirira-yekudzvanya pombi inoendesa mafuta kune yeruzhinji pombi yekupa mafuta pakumanikidzwa kwakakwira, uye iyo yakakwirira-yekumanikidza pombi yemafuta, pressure sensor uye ECU inoumba yakavharwa-loop oparesheni kuti inyatso kudzora kudzvanywa kwemafuta mumafuta eruzhinji. pombi, ichinyatso shandura kudzvanywa kwemafuta neiyo injini yekumhanyisa shanduko.Phenomenon.Hunhu hwayo hukuru ndeiyi:
1. Nguva yejekiseni yemafuta inoparadzaniswa zvachose kubva kumagetsi ekugadzirisa mafuta, uye kushandiswa kwejekiseni yemafuta uye nzira yejojo yemafuta inodzorwa neECU munguva.
2. Kumanikidzwa kwejekiseni yemafuta ega yega silinda, nzvimbo yekutanga uye nguva yejekiseni yemafuta inogona kugadziriswa maererano nemamiriro ekushanda ejini, kuitira kuti utsvage nzvimbo yakanakisisa yekudzora jekiseni yemafuta.
3. High fuel injection pressure uye pre-injection ye diesel inogona kuwanikwa.
